graded index

This paper prestens the principie on measurement of lightning current steepness meter.

提出用磁带测量雷电流最大陡度的基本原理,测量误差小于±5％。

The results indicate that the threshold voltage,the saturate voltage and the gradient factor change with temperature.

采用DMS 505显示器测量系统测量并分析了环境温度对TB3639型液晶光阀的电光特性的影响,结果表明:阈值电压,饱和电压和陡度因子均是温度的函数。
